Caution
When exchanging HEIDENHAIN components, you might come into contact with electronic
components.
Always assume that all electronic components and assemblies are endangered by
electrostatic discharge (ESD) and may be damaged by incorrect handling.
These ESD-sensitive components could also come into contact with a statically charged
object (tool, workbench, packaging, etc.)
Therefore, when exchanging MC, CC, HDR, drive assembly, buffer battery and all units with
openly accessible electronic components, observe the ESD measures!
When handling electrostatically endangered components or assemblies (e.g. exchange,
installation, shipping), always comply with the precautionary measures described in
IEC61340-5-1, IEC 61340-5-2 and IEC 61340-4-1.
Store and transport ESD-sensitive components in ESD protective containers.
Ensure during handling the proper grounding of the working area (e.g. tool, workbench,
packaging) and the person.
Inspect the ESD protection system regularly.
The following figure shows how a suitable working area could look in accordance with
IEC 61340.
1. Wrist strap with 1 MOhm grounding cable for grounding the person
2. Grounded connection for wristbands, floor mats, table mats etc. for equipotential
bonding
3. Dissipative shoes
4. Dissipative flooring or floor mat
